The winter solstice is right here in the present day (Dec. 21), marking the shortest day and longest night time of the 12 months for the Northern Hemisphere.
Because the astronomical begin of winter, in the present day is the second the solar reaches its lowest level within the sky as seen from Earth. At midday, it seems immediately over the Tropic of Capricorn, a latitude of 23.5 levels south, creating the least daylight of the 12 months for the Northern Hemisphere, which is tilted as removed from the solar because it will get.
With the sun tracking low across the horizon, its rays arrive at a shallow angle, spreading light over a larger area and reducing heating. It’s this lower solar angle, not our distance from the sun, that drives the coldest months of the year. But from this point forward, daylight will slowly begin to increase as we begin the slow march toward spring.
Earth’s seasons exist because our planet is tilted by 23.5 degrees on its axis. As Earth orbits the sun, different hemispheres lean toward or away from it, changing the intensity and duration of sunlight. When the Northern Hemisphere tilts toward the sun, we get summer; when it tilts away — as it does now — we have winter.
Meanwhile, the Southern Hemisphere is experiencing its summer solstice today, enjoying the longest day of the year.
Although many assume winter corresponds to Earth being farther from the sun, the opposite is true. Earth actually reaches perihelion, its closest point to the sun, early next month on Jan. 3, 2026. At that moment, our planet will sit about 91.4 million miles (147.1 million kilometers) from the solar, barely nearer than its common distance of 93 million miles (149.6 million km).
Many cultures mark the winter solstice as a second of renewal and the symbolic return of sunshine. Beginning tomorrow, daylight begins to develop once more, a reminder that brighter, hotter days are on the way in which.
